Analysis and Comparison the Dynamical Properties for Two Hyperchaotic Systems

In this paper , a new four-dimensions hyperchaotic system is proposes based on a three-dimensional Pan system by introducing a nonlinear state feedback controller, and we investigated some basic properties for this system numerically and analytically, we found the parameter c is effective on stability of new system at the point O(0,0,0,0) and has two roots form b d 1 2 , while has root 0 1 at the points 1,2 p , and we compare the properties of a new system with properties of another 4D hyperchaotic system and show the difference between them, Finally, an illustrative example is given.
